WARNING:
Brake fluid, if it leaks, will interfere with safe
running
and
immediately
discolor
painted
surfaces.
Check
the brake hoses for cracks and hose
joints for leakage before riding.
Brake pads
The extent of brake pad wear can be checked by
observing the limit line () marked on the pad.
When
the wear exceeds the limit line, replace the
pads with new ones. (see page 6-6)
Bleeding air from the brake fluid circuit
Air trapped in the fluid circuit acts like a cushion
to absorb
a large proportion
of the pressure de-
veloped by the master cylinder and thus interferes
with
the full braking
performance
of the brake
caliper. The presence of air is indicated by "'spongi-
ness'' of the brake lever and also by lack of braking
force.
Considering
the
danger
to
which
such
trapped air exposes
the machine
and rider, it is
essential
that,
after
remounting
the
brake
and
restoring the brakesystem to the normal condition,
the
brake
fluid circuit
be purged
of air in the
following manner:
e
Fill
up
the
master
cylinder
reservoir
to the
upper
end of the inspection window.
Replace
the reservoir cap to prevent entry of dirt.
e@ Attach a pipe to the caliper bleeder valve, and
insert the free end of the pipe into a receptacle.
e@ Squeeze and release the brake lever several times
in rapid succession, and squeeze the lever fully
without
releasing
it. Loosen
the bleeder valve
by turning
it a quarter
of a turn so that the
brake
fluid runs
into the receptacle; this will
remove the tension of the brake lever causing it
to touch
the handlebars
grip. Then, close the
valve, pump and squeeze the lever, and open the
valve. Repeat this process until the fluid flowing
into the receptacle no longer contains air bub-
bles.
Close
the
bleeder
valve,
and
disconnect
the
pipe.
Fill the
reservoir
to the
upper
line
in
inspection window.

NOTE:
When
bleeding
air
from
the
brake
fluid
circuit,
remove
the brake
lever adjuster @
from
the brake
lever as shown
in the Fig.
above.
After
bleeding
air from
the brake
system
is completed,
install the brake lever
adjuster. Replenish the brake fluid reservoir as
necessary while bleeding the brake system.
Make
sure
that there
is always some
fluid
visible in the reservoir.
